Zinc and Epoxy Coated Steel Reinforcing Bars

Providing customer reassurance that high performance corrosion resistant steel will meet a given set of criteria is the purpose of a new ASTM International standard recently approved by Committee A01 on Steel, Stainless Steel and Related Alloys. The new standard, A1055, Specification for Zinc and Epoxy Dual Coated Steel Reinforcing Bars, is under the jurisdiction of Subcommittee A01.05 on Steel Reinforcement.

“A1055 allows customers a level of comfort that they can credibly specify a dual coated reinforcing steel bar product and be assured that they are receiving what they have specified,” says Andrew Marquardt, product manager, Gerdau Ameristeel, and a member of the task group that developed A1055. According to Marquardt, the new standard will be most beneficial to state departments of transportation that require high performance corrosion protection of reinforcing steel bars in coastal environments as well as departments of transportation that use deicing salts on roads, bridges and decks. Marquardt notes that A1055 will also meet the needs of design engineers specifying steel product for buildings along a coast, wastewater treatment plants and facilities that use harsh chemicals.
